1.56÷3.9=
2.3÷0.46=
75.6÷18=
91.4÷9.7≈
(得数保留一位小数)
0.468÷0.29≈
(得数保留一位小数)
5.586÷0.72≈
(得数保留两位小数)

解:
1.56÷3.9=0.4,

2.3÷0.46=5,

75.6÷18=4.2,

91.4÷9.7≈9.4,(得数保留一位小数)

0.468÷0.29≈1.6,(得数保留一位小数)

5.586÷0.72≈7.76,(得数保留两位小数)

分析:根据小数除以整数的计算方法:按整数除法的方法计算,商的小数点要和被除数的小数点对齐;整数部分不够除,商 0,点上小数点继续除;如果除到被除数的末尾仍有余数,就在余数末尾 添0,再继续除.填写即可.
点评:考查了小数除以整数的计算法则,是基础题型.
